Investigate DMS migration issues with AWS DevOps Agent
DevOps & Developer Productivity Blog
This article demonstrates how to extend AWS DevOps Agent to investigate database migration issues using a Model Context Protocol (MCP) server with migration-specific tools and runbooks.
- Deploy an MCP server on AWS Lambda that provides 20 read-only tools for DMS migration diagnostics
- Agent autonomously correlates DMS task state, CloudWatch metrics, RDS Performance Insights, and logs to pinpoint root causes
- Covers pre-cutover readiness checks, validation failure investigation, CDC latency assessment, and post-cutover stabilization
- Includes 46 runbooks covering data validation, full load, CDC, connectivity, replication health, and cutover readiness
- Agent uses SigV4 authentication with IAM roles for secure, least-privilege access to migration tools
- Real investigations showed agent identifying issues like ValidationQueryCdcDelaySeconds race conditions in minutes versus manual troubleshooting taking 30+ minutes
This approach enables faster migration issue resolution by automating correlation of multiple data sources while maintaining security through read-only operations and IAM-based access control.
